INIPROVED RAILWAY-CAR. COUPLING.

The Schedule referred to in these Letters Patent land making part of the lame.

To all whom it may concern:

Be it known that I, ERNST A. BORNE, of Brookhaven, in the county of Lawrence, and State of Missis'sippi, have inventedl a new and valuable Improvement -in Coupling-Devices; and I do hereby dec-lare that the following is a full, clear, and exact description of the construction and operation of the saine, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1, of the drawings, is a front view of my coupling and uncoupling-device.

Figure 2 is a vertical central section through the same.

Figure 3 is a rear view, showing the manner of' attac-hing the spring p.

My invention relates to a means for coupling and uncoupling railroad-cars; and consists mainly in the construction and novel arrangement of devices, Where by the impact of the coupling-link in the buffer-head causes the descent ofthe coupling-pin, which is removed, when uncoupling, by the operator, acting upon the top of the car.

The letter A, of the drawings, designates a'bufferhead, having attached to it rigidly, a metal block, B, forming a support for the coupling-pin C.

The block B is 4slotted in its face, as at m', and in this slot slides a stud, n, formed on the coupling-pin, at about its centre.

The pin is thereby allowed freedom of movement, in the direction of its length, between the points i and It ofthe block B. These parts, t' and k, are perforated, to allow of the passage of the, coupling-pin, which also has a passage through an opening in the bottom of the-buer-head. A car is uncoupled by pulling a chain, c', attached at one end to the head of the coupling-pin, and at the other to a ring, which is secured to a hook, H, in the top of the car.

, The coupling-pin is thus drawn up as far as the stud n will allow, and entirely past the block P, which, being actuated by its spring p', immediately closes the opening at 7c, under the foot of the couplingpin G.

The spring p is attached to the rear of the block B, and near the top, and the block P worksin an opening in the lower part of the block B.

'The coupling-piu C being in the position last described, with its foot resting on the top of the block P, the coupling-operation is thus performed:

The coupling-link L, already attached to t-he car to be coupled, approaches, and enters the mouth of the buffer-head, passes on into the cavity, pressing back the spring p', and causing the block P to pass from vunder the foot of the pin O, which, now having no support, immediately descends as far `as the stud n will allow, coupling the cars.

The movement of tbe spring p is limited. by the length of the slots 1' and s, in the upper and lower surfaces of the butler-head, in rear of the block B.

The evil edeets of abr'upt concussion are avoided by introducing, near the rear end of the butler-head, the coiled spring w.

This spring is coiled around the cylindrical elongation, x', of the buffer-head, and works-between the shoulder y of the same,- and the support z', attached to the under part of the car-frame.

That I claim as my invention. and desire to secure by Letters `Patent, is

The coupler herein described, having buffer-head rik, slotted block B, spring 11', with block P, chain c',

-hook H,pin C, with stud u, and helical springw, coustructed and arranged substantially as specified.

In testimony that I claim the above, I have hereunto subscribed my name, in the presence of two witnesses.

ERNST A. BOHNE.
